The Official Warcraft Blog: Patch 5.2 introduces a new raid tier and PvP season, and so the higher tier currencies will be down-converted during maintenance. This time around there won’t be a soft cap, old Valor items aren’t changing to cost Justice, and we’re adding a new rank of PvP gear. Let’s break down exactly how it’s all going to harmoniously work together.
Valor -> Justice
All Valor is converted to Justice
Justice -> Gold
Justice above the 4000 cap is converted to gold at a rate of 47 silver per point
So let’s say the realms go down for the 5.2 patch and you have 450 Valor and 3800 Justice. Because of the 4000 Justice cap, you’d log back in after the patch is released with 0 Valor, 4000 Justice, and be 117 gold and 50 silver richer after the conversion.
With 5.2 we won’t be changing current Valor items to cost Justice, but they will be much cheaper (discounts from 50-75% off their current costs). . . . read full article
